Failure after instrumentation of code which has stackmap frames and array of more than 7 dimensions #839
Description
I am in the process of migrating a SW from Java 8 to Java 11. We are using JaCoCo for code coverage and I have found a problem when running the unit tests with JaCoCo tool (using ant).
JaCoCo fails when it instantiates a class that contains a primitive array with more than 8 dimensions. Please do not ask about the motivation of having an 8 dimensional array .... legacy code I have to maintain.
I have reduced the code to the min that reproduces the problem.
- The execution goes fine when I do not use JaCoCo/EclEmma or I use Java 8
- I have tested with two different JaCoCo versions , 0.8.2 and 0.8.3
Steps to reproduce
JaCoCo version: tested with 0.8.2 and 0.8.3
Operating system: MacOS HighSierra 10.13.6 and CentOS Linux release 7.5.1804
Tool integration: Ant 1.10.5 and Eclipse EclEmma 3.1.1.201809121651
Java Versions: OpenJDK 11.0.1 and OpenJDK 11.0.2
Use the following piece of code
import org.junit.Test;
public class PrimitiveArrayJacocoTest {
/**
* Test with a boolean array
*/
@Test
public void testBooleanArray() {
// Just instantiate the class
new BooleanArrayJacoco();
}
/**
* Test with an integer array
*/
@Test
public void testIntegerArray() {
// Just instantiate the class
new IntegerArrayJacoco();
}
public class BooleanArrayJacoco {
public BooleanArrayJacoco() {
// Declare a 8 dimension boolean array , if the amount of dimensions is reduced test does not fail.
boolean[][][][][][][][] array = new boolean[12][][][][][][][];
int idxDepth0 = 0;
if(array[idxDepth0] == null) {
array[0] = new boolean[4][][][][][][]; // Create new node with 4 array pointers
}
}
}
public class IntegerArrayJacoco {
public IntegerArrayJacoco() {
// Declare a 8 dimension integer array , if the amount of dimensions is reduced test does not fail.
int[][][][][][][][] array = new int[12][][][][][][][];
int idxDepth0 = 0;
if(array[idxDepth0] == null) {
array[0] = new int[4][][][][][][]; // Create new node with 4 array pointers
}
}
}
}
Expected behaviour
JaCoCo is able to run the tests with no failure.
Actual behaviour
Tests fail with the following stack trace

and running the testBooleanArray .... the same but with different ClassNotFoundException:
